Products Description of 3-MERCAPTOPROPIONIC ACID CAS#107-96-0

3-Thiopropionic acid is a direct raw material in organic chemicals and is used in pharmaceutical intermediates and electronic chemicals; it is used as an intermediate in the pharmaceutical Fenal, and it is also used as a stabilizer for polyvinyl chloride. Like thioglycolic acid, it can be used in transparent products and has very good thermal stability, better than other stabilizers; it is also used as an antioxidant, catalyst and biochemical reagent.
